Extending the Applicability of Diffraction-Based Drop Sizing Instruments


Modifications to a commercial laser diffraction-based drop sizing instrument are described which allow the unit to be used for drop sizing in sprays evaporating in high-temperature air, and under conditions of very high ambient light levels. These modifications have permitted drop size measurements in sprays evaporating in air at temperatures and pressures as high as 700 K and 586 kPa.
